Elliptera jacoti Alexander, 1925

Alexander, 1925b: 388; Savchenko and Krivolutskaya, 1976: 113; Savchenko, 1983: 109.

Head black, covered with gray pruinosity, especially anteriorly and at the margins of eyes. Antenna brown, 16-segmented. Male antenna 1.7-2.4 mm long, female 1.4-1.8 mm. Scape brown with darkened apex, cylindrical. Pedicel brown, oval. Basal flagellomeres with light brown base and darkened apex, distal flagellomeres dark brown. Flagellomeres narrow basally, strongly dilated at about two thirds of length, with distinc apical pedicels. Apical flagellomere elongate, nearly cylindrical, longer than preceeding segment. Verticils approximately as long as respective segments. Dense short pubescence covers all flagellomeres. Rostrum dark brown dorsally, yellowish brown ventrally. Palpus dark brown, covered with short erect setae.

Thorax brown, covered with gray pruinosity. Pronotal scutum brown, posteriorly ringed with light brown, sides covered with sparse pruinosity. Mesonotal prescutum uniformly shiny brown dorsally, sides mate gray covered with dense pruinosity. Prescutal stripes not expressed. Scutellum brown, slightly lighter posterio-laterally. Mediotergite uniformly brown, covered with sparce pruinosity. Pleura uniformly brown, covered with gray pruinosity. Wing tinged with brown. Male wing ( Fig. 4A ) with widened distal part of cell sc, thus tip of wing is blunt and widely rounded. Female wing ( Fig. 4B ) with usual, not widened distal part of cell sc, thus wing apex is more narrow, than in male. Cell r 3 distally strongly widened in both sexes. Discal cell missing, basal deflection of vein CuA 1 some distance before branching point of M. Both anal veins long and nearly straight. Frontal wing margin slightly darker than rest membrane of wing. Stigma indistinct or completely lacking. Cord surrounded by dark band. Haltere with dark brown knob and yellowish base of stem. Coxae yellow with testaceous bases. Darkening on frontal pair more intense than on second and posterior pair. Trochanters yellowish, rimmed with black distally.

Basal sternites of male abdomen light brown, distal sternites dark brown. Sternites of female abdomen light brown. Male genitalia ( Fig. 4D ) rusty brown. Ovipositor ( Fig. 4G ) with tenth tergite dark brown, cercus and hypovalvae yellowish brown. Cercus with rised apical part.
